Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626320, here are decompositions:

19 + 8626301 = 8626320
23 + 8626297 = 8626320
37 + 8626283 = 8626320
71 + 8626249 = 8626320
83 + 8626237 = 8626320
139 + 8626181 = 8626320
151 + 8626169 = 8626320
179 + 8626141 = 8626320

Showing the first eight; more decompositions exist.
